Hybrid power system 10 can be operated under various modes, and working condition of vehicle is depended in the selection of mode of operation, such as accelerator position, brake pedal position, wheel velocity etc.For example, in the time that driving engine 14 provides moment of torsion, motor/generator 40A/40B idle running and torque-transmitting mechanisms 48 and 49 to be engaged to input link 18, first is fixingly established than mode of operation.When driving engine 14 cuts out, motor/generator 40B as electrical motor when providing moment of torsion, motor/generator 40A idle running simultaneously and torque-transmitting mechanisms 48 to be engaged by the second compound planet gear 30 to output link 19, pure electronic mode of operation is established.Be controlled as while providing moment of torsion by the first compound planet gear 20 to output link 19 when input brake 54 is engaged input link 18 and bent axle 17 are grounding to static component 46 and motor/generator 40A, the second pure electronic mode of operation is established.When driving engine 14 is when input link 18 provides moment of torsion, motor/generator 40A, 40B to be controlled as electrical motor or electrical generator and only torque-transmitting mechanisms 48 is engaged, the first electric shift mode of operation is established.The first electric shift pattern is input diffluence formula.When driving engine 14 is when input link 18 provides moment of torsion, motor/generator 40A, 40B to be controlled as motor or electrical generator and only torque-transmitting mechanisms 49 is engaged, the second electric shift mode of operation is established.The second electric shift mode of operation is compound shunt mode.By torque-transmitting mechanisms 48 being engaged and motor/generator 40B being controlled as being used as electrical motor so that output link 19 rotates in opposite direction, thereby set up pure electronic reverse gear mode of operation.
In the present embodiment for the elastic component of torsion spring 50 is operatively connected to input link 18 and bent axle 17.The first end 52 of spring is connected to along with input link 18 and bent axle 17 rotate.Can be engaged by controller by selectivity joint input brake 54, so that first end 52, input link 18 and bent axle 17 are grounding to static component 46.In the time that engine crankshaft 17 rotates along the forward direction consistent with the preflow push of vehicle with input link 18, the unidirectional torque transmission mechanism 56 that can be described as free-wheel clutch or uni-directional brake allows the second end 58 of spring 50 to rotate, but when input link 18 with bent axle 17 is attempted to rotate in opposite direction and/or in the time that reaction torque is applied to unidirectional torque transmission mechanism 56 in opposite direction, thereby unidirectional torque transmission mechanism 56 locks the second end 58 is grounding to static component 46.
When authorized while being switched to electric shift mode of operation from electric-only mode or during the cold start of driving engine 14, spring 50 is used to provide the starting of spring torque with auxiliary engine 14.Specifically, for fire an engine 14 to be switched to any electric shift mode of operation from pure electronic mode of operation (motor/generator 40B provides moment of torsion and torque-transmitting mechanisms 48 to be engaged to output link 19 under this pattern), can be used to the rotation of auxiliary input link 18 and bent axle 17 from the moment of torsion of the spring 50 of reeling in advance, with fire an engine 14.
Spring 50 can be by using motor torque to be wound.Be disengaged by free-wheel clutch 56 overruns (overrun) and input brake 54, vehicle 10 can be advanced by driving engine 14.Light braking can be by pedal order (be brake pedal under press to controller transmitted signal) transmitted signal.One or two in motor/generator 40A, 40B can be controlled to as electrical generator work, and the torque axis of output link 19 is changed to preserved electric energy, thereby slows down and finally stop input link 18 and engine crankshaft 17.Alternately, or extra, and input brake 54 can be employed to slow down and finally stop input link 18 and engine crankshaft 17.In the time that vehicle 10 is sufficiently slowed down, regenerative brake no longer includes advantage, and friction brake on wheel (not shown) can be used to make vehicle stop.In the time that pedal order changes to reduce or reduces regenerative brake, regenerative brake also can stop.
By effectively making vehicle slows, input brake 54 do not need to be engaged to prevent that bent axle 17 from rotating forward, and motor/generator 40A as electrical motor work so that the first end 52 of input shaft 18 and spring 50 turns round (along with the direction of opposite direction of pushing ahead vehicle).Because the second end 58 is because the unidirectional torque transmission mechanism 56 of locking is grounded, therefore spring 50 the forward direction rotation with respect to bent axle 17 is folded backward around.By spring 50 is reeled like this, input brake 54 can be re-engaged, and with the spring 50 that keeps reeling, and one or two in motor/generator 40A, 40B provides moment of torsion to push ahead vehicle.Engine friction and compression also can contribute to keep the spring of coiling, and if engine friction and compression are enough, can not need input brake 54.
In the time that the working condition of vehicle instruction driving engine 14 such as car speed or pedal order should be reset, motor/generator 40A, 40B are controlled to prevent apply backward moment of torsion on input brake 54, thereby and input brake 54 be released discharge reel spring 50.Spring 50 by unreel, causes engine crankshaft 17 to rotate forward along forward direction, thereby auxiliary engine 14 provides little forward direction moment of torsion or do not provide forward direction moment of torsion at motor/generator 40A, 40B and starts.For example, if dynamical system 10 is operated in motor/generator 40B and is used as electrical motor to provide to output link 19 under engaged the first pure electronic mode of operation of power and torque-transmitting mechanisms 48, in the time that input brake 54 is released, the spring 50 of reeling is by the reaction torque using from the uni-directional brake 56 engaging, do not use or use from motor/generator 40B for providing reaction torque necessary a small amount of moment of torsion, and not using or use from a small amount of moment of torsion of motor/generator 40A provides moment of torsion with fire an engine 14 to input link 18.Therefore, the peak power load on dynamical system during engine starting 10 is minimized.Motor/generator 40B is for example specifically designed to propelling under throttle gate during engine starting is opened the critical condition of (throttle tip-in) (the indicated requirement of accelerating for vehicle by the pressure on accelerator pedal).
